The mini valve has added so much value for me as an owner of the M.V.S. When I want to shake up my routine, or just absolutely maximize the amount of flavor I can pull from my DynaVap tips, I’ll switch my XL valve for this and experiment, usually with completely hands-free cooling functionality. Two different experiences, one amazing product ecosystem that’s manufactured with a level of quality and care rivaled by VERY few in the industry. Hats off to Mr. Simrell.

Everyone should own a mini MVS. Its been a daily driver in my arsenal for years now and lives up to the hype. The mini valve and regulator are perfectly machined. The fluidity in turning to adjust the airport feels as premium as the device looks. My only wish is that it was still offered in different ano colorways.

Finally I get something that's worth the cost. I'm so happy with the stubby MVS. At 58 I finally quit smoking. --so tastey!

I picked up this mini valve to shorten my XL MVS. Exquisite workmanship as usual with Simrell, not a mark or blemish anywhere to be seen. Really nice to be able to swap and change between short and XL depending on use case or just mood.
Be sure to check your condenser is suitable as there have been a few changes over the years. You can cut down an XL condenser or even use a Dynvap short condenser in the Simrell mouthpiece.
Overall 10/10

The MVS is a stylish and flavourful piece, paired with the helix tip, it's a work of art. Love the modular design got me mixing and matching all my dynavap products for days with each piece brings a different kind experience. Highly recommend if you got a few dollars to spare.
